麦后复种3个芜菁品种的产量相关因素比较分析

Comparative and Analysis of Yield Related Factors to Three Turnip Cultivars Multiple cropping

以新星圆、卜留克、农家品种3个芜菁品种为试验材料进行麦后复种,比较分析3个品种的生长发育特性及产量。结果表明:3个品种的叶面积、SPAD值、叶片鲜和干物质量总体呈先增加后减小的变化趋势,其中农家品种在生长发育过程中保持较高的叶面积和SPAD值,前3次取样中其叶片鲜、干重均高于或显著高于其他2个品种。根冠比、肉质根的鲜、干物质量呈逐渐增加的趋势,农家品种各取样时期的肉质根的鲜、干物质量均高于其他2个品种,收获期的产量为农家品种>新星圆>卜留克,农家品种的产量达71037kg/hm^2,显著高于其他2个品种。由此可见,麦后复种当地农家品种的产量相关因素及经济产量都明显优于另外2个品种,适合河套地区进行麦后复种。

By using the 3 turnip Cultivars of Xin Xingyuan,Bu Liuke and Nongjia for the test material after wheat re-planting,to study the growth and development characteristics and yield of the three varieties.The results showed that:The leaf area,SPAD value,leaf fresh and dry matter quality of the three turnip varieties showed a trend of first increasing and then decreasing,in which the Nongjia cultivars kept higher leaf area and SPAD value during their growth and development.Among them,the fresh and dry weight of the leaves were higher than or significantly higher than the other two varieties in the first three samples.Root shoot ratio,the fresh and dry matter mass of fleshy roots showed a trend of increasing gradually.The fresh and dry matter mass of Nongjia varieties in each sampling period was higher than that of the other two varieties,and the yield was Nongjia> Xin Xingyuan> Bu Liuke at the harvest stage.The yield of the Nongjia varieties reached to 71 037 kg/hm^2,which was signif-icantly higher than that of the other two varieties.Results showed that the yield-related factors and economic yields of the Nongjia varieties multiple cropping after wheat are obviously superior to those of the other two varieties,which is an excellent turnip variety suitable for growing in Hetao area multiple cropping after wheat.
